So this is a normal wow grind and I LOVE IT
Spent days reading article after article looking at other players scary stories about how they spent a week farming and got one crystal…Bollocks
Took my mining main to Winterspring yesterday (Beautiful Zone) and i can say that after the Frostsaber Mount Grind, and i was there from 15:30pm GMT and spent 4hrs and got 61 (yes 61, hardly a poor number). Complete loops around the area stopping at the caves at Mazoril and the Yeti cave on the east side.
This grind could be a whole lot worse, every other Crystal that drops from this vein is a far worse drop rate.
I am banking on 6 1/2 hours to get the 90 crystals (bought 10 & f**k that) i need for Thunderfury so 8hrs here at the most for 100.
Anyone who spent time in Icecrown flying loop after loop for hours, days & weeks mining Thorium in WOTLK will be transported back to a happier time, stick on a few tunes on and enjoy.
Good Luck!
